The Infinite Worlds of H.G. Wells S01E03 - The Truth About Pyecraft & The Stolen Bacillus

In Part Three, "The Truth About Pyecraft," a brilliant mathematician wants to lose weight, but getting his wish just might cost him more than he could possibly imagine. Finally, in "The Stolen Bacillus," a flask that may hold a dangerous virus is missing and Wells gets on the case to hunt down the thief.
As the elderly Wells tells his stories, he discovers that Miss McGillivray has a secret of her own, and meeting her may affect him in a more profound way than he could ever have dreamed.
